When astronomers look deep into the early universe, the expectation is simple. You should see young galaxies still assembling ...

Supermassive black holes spiral towards each other in this simulation created by NASA's Goddard Space Flight Center that shows how they glow in ultraviolet and X-ray light. The black holes are only 40 ...

Astronomers were puzzled by a black hole around 50 million times the mass of the sun with no stars, spotted by the James Webb ...

Nearly every galaxy has a supermassive black hole in its core. Whether the black hole forms first and then the galaxy around ...

Black holes are among the most extreme objects in the universe, and now scientists can model them more accurately than ever before. By combining Einstein’s gravity with realistic behavior of light and ...

A recent study published on arXiv has revealed a black hole so massive and so ancient that it challenges long-standing models ...

A new simulation could help solve one of astronomy’s longstanding mysteries—how supermassive black holes formed so rapidly—along with a new one: What are the James Webb Space Telescope’s (JWST) ...

New simulations suggest magnetic fields hold the key to forming black holes that defy known mass limits. When powerful magnetic forces act on a collapsing, spinning star, they eject vast amounts of ...

At the center of the Milky Way galaxy exists a supermassive black hole that's more than four million times the sun's mass. A human traveling to the black hole's surface, known as the event horizon and ...

Scientists at the University of Colorado Boulder may have solved a pressing mystery about the universe's gravitational wave ...

A neutron star's final moments may spark violent starquakes, monster shock waves, and even a fleeting, never-before-seen object called a black hole pulsar. When you purchase through links on our site, ...
